PLANE SIEVE.

JAQUET, a

citizen of France, residing at- Strasbourg- Kcenigshoffen, Alsace,

France,

have iiivented new and useful Improvements in Plane Sieves, (for which I h patent in Germany, No. 328 1916 and have filed applicati ave obtained a ,719 of July 26,

ons in France,

December 11, 1920, No. 156; Belgium, March 23, 1921, NO. 235,863, March 29, 1921 No. 11,809), following is a specification.

This invention relates to in plane sieves, the object be an improved device of this means of which. tually sifted. The invention and Switzerland,

of which the improvements ing to provide character, by

material may be more effecconsists in the construction and arrangement of devices hereinafter described and claimed.

In the drawings Fig. 1 is a plan of a sieve constructed in accordance with this invention.

Fig. 2 is a longitudinal sect-ion on the line A A of Figure 1 and Figure 3 is a cross section on the line C D of Fig. 1.

In the embodiment of sieve as shown in Figure its length into a number of and 3, each division being invention the 1 is divided along divisions 1, 2 either circular hexagonal octagonal or polygonal and of which the inlets and outlets narrower than the sieve surfaces. divisions are made much wider d and 5 are The sieve than said inlets and outlets so that the material in consequence of the circular mo vementof the sieve can spread out and thus completely cover and utilize the sifting surface.

The material to be sifted cannot be thrown in a Zig zag path from one side to the other as the two walls 7 and 8 are some distance apart. In this manner a circular movement is imparted to the material to be sifted which results in an intensive sifting action. The sifting surfaces are thus completely and entirely utilized so that the efficiency is considerably increased.

According to the composition of the material to be sifted one side of the sifting surface may be provided with transporting plates 9 so as to impart a greater or less speed to the material to be sifted.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is 5 In a plane sorting device a sieve surface having cross traverses, whereby above each transverse on both sides of the longitudinal. walls of the sieve surface wedge shaped corners are disposed, which consist of frames whereby the individual cross compartments receive a round or approximately round sieve surface, said corner serving at the same time as inlet and outlet passages between the individual compartments and transporting plates arranged atone side of the cross compartments and extendingpartly thereacross.

in witness whereof I aftie: my signature.

CHARLES JAQUET.
